I haven't seen this mentioned elsewhere, but the team called up this week is devoid of players raised overseas. There are no U.S. - German dual nationals, for example. No Johnson, Brooks, Chandler or Jones. Also no Johannsson or Carter-Vickers.
The closest you come is Darlington Nagbe, who settled in the U.S. at age 11.
It would be easy to make too much of this - especially given all the comments around it a year ago. I don't think this reflects an intentional approach by Arena. The only surprise omission is Johnson, and his form has not been strong for Club or Country.
Still it is interesting to note that our country will rise or fall this weekend on the backs of a group of players mostly born in and entirely raised in America, which means their formative years were spent developing soccer skills in the states. It will be interesting to see if a group developed in America can get the job done.
